Manufacturer of Metal Alloys
This project involved the decommissioning of a nickel hydroxide wastewater vault inside a facility in southeast Michigan that manufactures metal alloys such as nickel magnesium, nickel-metal hydride materials, and custom engineered nickel calcium alloys for hydrogen storage and nickel vanadium alloys for shape memory applications. The client retained ECS because we were able to assemble an experienced team including ECS staff, soil boring contractor, analytical laboratory and an environmental contractor.
The water and sludge within the vault were sampled and analyzed for disposal characterization, prior to being removed and transported for disposal. The environmental contractor then pressure washed the vault and drain lines and removed/disposed of the rinsate. The drain lines were plugged, the vault was filled with clean aggregate and capped with concrete. ECS directed the activities and documented the results in a Closeout Report. In addition, ECS conducted a subsurface investigation in the area of the vault and determined that no release to the environment had occurred. ECS also prepared a written professional opinion that the vault did not meet the definition of an Underground Storage Tank.
